Kurzfassung

The desired coexistence of robotic systems and humans
in the same physical domain, by sharing their workspace
and actually cooperating in a physical manner, poses the very
fundamental problem of ensuring safety to the user. In this
paper we will show the influence of robot mass and velocity
during blunt unconstrained impacts with humans. Several
robots with weights ranging from 15–2500 kg are impacted at
different velocities with a mechanical human head mockup. This
is used to measure the so-called Head Injury Criterion, mainly a
measure for brain injury. Apart from injuries indicated by this
criterion and a detailed analysis of chest impacts we point out
that e.g. fractures of facial bones can occur during collisions at
typical robot velocities. Therefore, this injury mechanism which
is more probable in robotics is evaluated in detail.
